Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33619980, here are decompositions:

7 + 33619973 = 33619980
61 + 33619919 = 33619980
137 + 33619843 = 33619980
179 + 33619801 = 33619980
181 + 33619799 = 33619980
223 + 33619757 = 33619980
227 + 33619753 = 33619980
241 + 33619739 = 33619980

Showing the first eight; more decompositions exist.
